• Extended PTFE Wedge: Features a longer wedge profile to maintain sealing integrity even when the shaft wobbles.
• Bearing Support (Optional): Can be integrated with a steady bearing to provide additional shaft support and protect the seal faces.
Key Features
• Agitator-Specific Design: Accommodates larger radial runout (up to 0.5mm) compared to standard pump seals.
• High-Pressure Capability: Balanced design capable of holding vessel pressures up to 40 bar during reaction cycles.
• Dry-Run Options: Can be configured with special Carbon faces for top-entry mixers where the seal operates in the gas phase.

Workshop
This workshop is equipped with professional processing equipment and integrated with standardized material warehousing management, enabling a one-stop production process from precision machining to finished product delivery. It ensures part machining accuracy and production efficiency, meeting various high-specification manufacturing requirements.
Product Research, Development and Testing
Our Product R&D and Testing focuses on optimizing seal performance through advanced simulation and material analysis. All seals undergo rigorous trials, including thermal cycling and pressure tests, to ensure durability, minimal leakage, and long service life in demanding industrial environments.
Industry Solutions
Case Study
Polymerization Reactor: A high-pressure reactor (30 bar) was leaking toxic monomers. Standard seals failed due to shaft deflection. We installed this High-Pressure PTFE Wedge Seal. Its robust tracking ability handled the movement, maintaining a zero-leak environment.
Testimonials
The shaft wobble on our old mixer destroyed every seal until we tried this one. It's built like a tank.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Can this run dry in the vapor space?
A: Yes, if equipped with our special Dry-Running Carbon face material. However, for high pressures, we often recommend a double seal with a liquid barrier for cooling.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
